What ETS Licence do I need?

The KNX Engineering Tool Software (ETS) is the programming software used for all KNX systems. ETS, which is Windows 10 compatible, is licenced by KNX.org, is manufacturer neutral and allows the commissioning of all KNX certified devices in that system.

There are various licence types available, which all have the same programming structure, and licence type is dependant mainly on the number of programmed devices which are required. All licences function via a KNX ETS USB dongle and the most recent ETS software version is ETS5.

How do I buy an ETS licence?
